Application filed December 19, 1910.

To all whom t may concern:

Be it known thatl, FRANCIS L. CLARK, a

.citizen of the United States, residing atlansas City, in the county of Wyandotte and State of Kansas, have invented certain new and useful improvements in Uil-Burners, of which the following is a specification.

This invention relates to liquid fuel or hydrocarbon burners, and aims to provide a burner which is.so constructed that oil or other liquid fuel may be drawn or sucked into same by means of steam, hot air or other fluid, so as to atomize and spray the fuel for providing a maximum heating effect with a minimum supply of fuel.

It is also the object of the present invention to provide a burner of the character indicated which may be employed an `inje'ctor burner for boilers, and the like, the same being simple and inexpensive in construction and effective in its operation.

The present invention also comprehends the production of a burner of the class described wherein the flow of liquid fuel may be regulated, or stopped, by means for regulating the flow of steam through the burner.

In addition to the foregoing objects this invention also aims to generally improve liouid fuel burners of the type indicated.

`With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiment in the accompanying drawings, wherein Figure 1 is a longitudinal central section of the burner. Fig.`2 is a sectional view taken on the line H-H of Fig. 1. Fig. 3 is an enlarged sectional detail taken on the line lll-IH of Fig. l.

Referring specifically to the drawings, the present burner embodies a tubular body l, which is rprovided ywith interior and eXterior screw threads at its forward and real* ends, respectively. The body 1 is provided with a. radially projecting socket 2 intel'- mediate its ends for the engagement ofthe fuel pipe 3 and diametrically opposite the Specification of Letters Patent.

socket 2 the body is provided with a radiallv projecting socket 4 for engagement of the steam pipe 5. The body l is also provided with a partition 6 therein which is arranged forwardly of the axis of the sockets 2 and i and which provides a rear chamber 7 and a front chamber 8 within the body. The body 1 also has a diagonal passage 9 leading from the rear side of the socket 2 to the rear chamber l at ay point in rear of the partition 6 and has another diagonal passage 10 leading from the forward side of the socket 4 to the rear end of the forward chamber 8.

A tubular stemll is arranged axially or concentrically within the body l, with its ends protruding beyond the ends of the body. and the rear end being closed. The stem 11 passes through a sleeve.12 arrangedwithin the chamber 7, which sleeve is slidable in the' said chamber and has the exte-` rior and interior shallow annular channels 13 and 14, respectively. These channels 13 rand 14 are of considerable width, the sides of the channels terminating short of the ends of the sleeve.- The sleeve is also pro- '18 fits into the rear end of the body 1,s'iiitable packing 19 being disposed between the gland 1S and the rear end of the sleeve l2 around the stem 11. A cap 20 is screw threaded on the rear end of the body to bear against the gland 18 in order to force the gland forwardly or inwardly, and the gland being forced inwardly causes the packings 17 and 19 to be pressed against the walls of the chamber 7 and against the stem 1l in order to prevent leakage, as will be apparent. The stem 11 passes through the cap 20 and is provided with external screw threads 21 engaging the said'cap, so that lwhen the stem is rotated, the same will be tures 16 complementing the apertures'l, so

. rupting the fuel supply, or the sleeve 12 that the liquid fuel may ow from the pipe 3 into the stem 11. It will he noted that the channels 13 and 14 will permit the sleeve to move longitudinally and will permit the stem to move longitudinally without intermay he reversed in order tol vary the 'position of the apertures 16 relative to the apertures. 15, the apertures .15.heing than the other end,

' A tubular lengthening member 23 is screw threaded into the forward end of the body 1, and a nozzle 2l is screw threaded .onto the forward end of the vvtubular lengthening member 23, the saidnozzle'having a forwardly tapered and const-ricted outlet pas-A sage 25 providing a rearwardly facing beveled shoulder or seat. A guide collar or ring 26 1s arranged conccntrically within me nozzle 24 in rear of its seat and is con-` nected to the inner walls of the nozzle by means of the dianietrically opposed webs 27, thus providing arcuate passages 28 around the collar 26 to the outlet'passag'e The forward end of the stem 11 is reduced and enters the guide collar 26 as designatedby the numeral 29, and a nozzle 3() is screw threaded into and seated against the forward end of the stem l1, thenozzle 30 having the reduced tip 31 entering the outlet passage 25 of the nozzle 2d. The reduced tip 31 provides a conical shoulder on 'the nozzle 30 facing forwardly, the shoulder of the nozzle 3() corresponding with and complementing the 4beveled seat of the nozzle 2li.. The nozzle 30 1s of greater diameter' than the diameter of the passage 25, so that when the nozzle 3l) is moved forwardly, the same' will tend to close the passage 25, and as the stein is moved rearwai-diy;` the passage loetween the shoulders is increased.

ln use, the pipe 3 is connected to a suit ahle source of liquid fuel and the pipe 5 connected to a suitable source of steam, hot or other suitable. fluid, it being preferable to have the source of fuel, such as a tank or the like, located below the burner so that the fire; irust he drawn into the burner, Then when thevs'tem 11 is turned to move rearwardly, the nozzle 30 will move away from the seat of the nozzle 2l so as to per mit the steam to pass through the outlet passage 25, from the chamber within the nozzle 2l, the tubular lengthening member 23 and lthe forward portion of the body 1. rlhe steam in passing hetweenthe shoulders of lthe vtwo nozzles will he directed. toward the axis of vthe nozzles or toward the ltip' 'will--becaused to pass over the free end of arranged closer to one end of thesleeve 12 vacuum, in which event, the fuel will be drawn from the supply pipe 3 through the passage 9 .and the apertures and 16 into the stem 11 and then through the tip 30. The oil' or other liquid fuel is thus raised into'the burner and 1s atomized and sprayed, so that the particles of'oil will thoroughly commingle with the same for the production of a flame of high degree.

lt will he noted that the stem 11 may be rotated so as to be moved forwardly or rear# wardly without interrupting the fuel supply',

and as lthe said stem is moved forwardly or rearwardlythe supply of steam is correspondingly diminished or increased, which will accordingly decrease or increase the quantity offuel discharged from the nozzle 30. By moving` theistem forwardly sufficiently, the conical shoulder of the valve 30 may he seated against the beveledseat of the nozzle 2d, so as to close the passage through the nozzle 24, thereby preventing the discharge of steam and correspondingly cuttingoil' the discharge of fuel. The

30 he adjusted relative to the forward end of the stem'll by screwing the the proper direction, and when 30 'is screwed rearwardly so as to seat against the end of the stem 11, the shoulder formed bythe reduced portion 29 of the stem is adapted to strike the collar 26 prior to the contactof the conical shoulder of the tip 30 with the 'beveled seat of the nozzle This, therefore, will ordinarily leave a small passage for the restricted discharge of the steam, which discharge will he so small as not to cause a suc tion sutlicicnt to lift the fuel, but at the same time preventing the pressure of the steam from rising excessively.l

From the foregoii1,9,` taken in connection with the drawings, the advantages of the present'hurner will he manifest, and will appear that the objects aimed at have been carried out in a satisfactory manner.

Having thus described the invention, what is claimed as new is:

1; An oil burner embodying a body having' a pair of diametrically opposite pipe engaging sockets intermediate its ends and a partition therein forming forward and rear chambers, the body, being-; provided with a passage leadingr from one socket to the forward chamber and with another passage having an annular series pf apertures nearer one end than the `other, the forward end of the sleeve projecting beyond the latter passage so that the passage communicates withthe exterior =channlpftlle sleeve, a member engaged to the rear of the body, a tubular stem adjustable through' the said member inerme l and passing through the sleeve and partition, the stem being prQ-Vfled with an an! miler Series of apertures., complementing the aforesaid epertiires, of the sleeve., eoperf ating nozzles attached t0. the orwald ends 0f the Stem and body;` and peeking disposed between the fSpeCtVe ends lof the sleeve and the Partition and said member.

2. An oil burner embodying a body having a pair of diametrically opposite pipeengaging sockets intermediate its ends and a partition therein forwardly of the axis of the said sockets and forming forward and rear chambers, I'the bQdX being provided with.
